Doppler Shift in Andreev Reflection from a Moving Superconducting Condensate in Nb/InAs Josephson Junctions
F. Rohlfing, G. Tkachov, F. Otto +4
We study narrow ballistic Josephson weak links in a InAs quantum wells contacted by Nb electrodes and find a dramatic magnetic-field suppression of the Andreev reflection amplitude…
Andreev reflection at high magnetic fields: Evidence for electron and hole transport in edge states
J. Eroms, D. Weiss, J. De Boeck +2
We have studied magnetotransport in arrays of niobium filled grooves in an InAs/AlGaSb heterostructure. The critical field of up to 2.6 T permits to enter the quantum Hall regime.…
Skipping orbits and enhanced resistivity in large-diameter InAs/GaSb antidot lattices
J. Eroms, M. Zitzlsperger, D. Weiss +6
We investigated the magnetotransport properties of high-mobility InAs/GaSb antidot lattices. In addition to the usual commensurability features at low magnetic field we found a bro…
Reentrant behavior in the superconducting phase-dependent resistance of a disordered 2-dimensional electron gas
S. G. den Hartog, B. J. van Wees, Yu. V. Nazarov +2
We have investigated the bias-voltage dependence of the phase-dependent differential resistance of a disordered T-shaped 2-dimensional electron gas coupled to two superconducting t…
Suppression of the Coulomb interaction contribution to the conductance by a parallel magnetic field
S. G. den Hartog, S. J. van der Molen, B. J. van Wees +2
The Coulomb interaction contribution to the conductance is investigated in a phase-coherent disordered 2-dimensional electron gas, which resistance can be varied by an overall gate…
